A temporary power distribution device for receiving and distributing electrical power from an external power supply on a temporary basis. The temporary power distribution devices can include a plurality of electrical outlets and/or electrical communication outlets and may include additional safety features for the loss of power and/or the notification of an emergency condition. The temporary power distribution device may be portable and is meant to be portable even during use.
This application claims priority to and benefit of U.S. provisional patent application 62/767,684, filed Nov. 15, 2018, which is hereby incorporated by reference in its entirety as if fully set forth herein.
BACKGROUNDThe present invention is generally related to electrical devices, and more specifically to power outlet and conversion devices. More specifically still, the invention is directed toward devices which can receive electrical power from an external source and convert it into multiple regulated outlets while providing other advantageous features directed toward construction and industrial fields.
In many instances when the use of electrical power tools is required, including building construction, natural emergency relief and reconstruction, military efforts and military base construction, mining, and the like, workers often find themselves without permanent sources of electrical power to power said tools. Known methods for linking power tools to a temporary electrical source generally include running electrical extension cords directly from a generator and plugging tools directly into said extension cord. In some cases, extension cords may be tied or stapled to saw-horses or other temporary structures, but these may prevent a fire hazard and cannot prevent power surges and other hazards. Additionally, this requires constant plugging and unplugging to use different tools. Other solutions may include using tools that run on batteries while alternate batteries are charged by a gasoline generator. This creates additional inconveniences and can increase construction time and costs.
Such solutions also create inadvertent dangers, as a loss of power loss can cast a construction site, especially one located inside a building, mine, etc., into complete darkness. If power is lost because of a fire or other hazardous conditions which may pose immediate and catastrophic danger, the only emergency alert for workers in other areas or on other floors of the site is direct contact with workers already aware of the emergency condition, either via radio or wireless device or shouting.
It may be advantageous to provide a temporary power distribution device which has at least one of the following features: multiple outlets to power numerous devices simultaneously; an internal power source for providing temporary illumination when external power is lost; an audible alarm triggered when an emergency condition exists; the audible alarm being powered by either of the external power source or an internal battery; a beacon light triggered when an emergency condition exists; the beacon light being powered by either of the external power source or an internal battery; and a wireless receiver and wireless broadcaster being included to link the power distributions device to other power distribution devices such that an emergency condition may be communicated to the full network of power distribution devices.
SUMMARYBriefly speaking, one embodiment of the present invention is directed to a temporary power distribution device. The temporary power distribution device may include a power station housing having a base and a tower.

Described another way, prior to being moved, the temporary power distribution device 40 has a horizontal axis 150 defined by the base 54 that is roughly parallel to the support surface 152 while the base 54 is resting on the support surface 152. When the base 54 is resting generally flat against a support surface 152, such as a floor, it is preferred that the horizontal axis 150 defined by the base 54 is roughly parallel to the support surface 152. The tower 44 defines a vertical axis 50 that is roughly perpendicular to the horizontal axis 150. As the user pulls backward and downward on the handle 68 with his or her hand 148 while exerting pressure on the foot prop 66 with his or her foot 146, the base 54 preferably raises from the support surface 152 As that occurs, the angle of the horizontal axis 150 relative to the support surface 152 taken along the front side 56 of the device 40 increases until the device 40 rests only on the wheel 60. Simultaneously, the angle of the vertical axis 50 relative to the support surface 152 taken along the rear side 58 of the device 40 decreases from roughly 90 degrees to an angle between 89 degrees and 1 degree. The relationship of 1.) the angular position of the horizontal axis 150 relative to the support surface 152 taken along the front side 56 of the device 40; and 2.) the angular position of the vertical axis 50 relative to the support surface 152 taken along the rear side 58 of the device 40 is therefore inversely proportional.

The device 40 may also include a signal receiving network device 126 such as a wireless or Bluetooth router, internet enable processer, and the like. The signal receiving network device 126 is preferably configured to receive an alert signal from another temporary power distribution device 40 within a predetermined range via a wireless signal 141. The temporary power distribution device 40 preferably also includes a signal transmitting network device 128 for sending the alert signal to other temporary power distribution devices within the predetermined range via a wireless signal 141. In other words, a network of power distribution devices 140 is formed of a plurality of the temporary power distribution devices 40 which are networked wirelessly, connected via a wireless signal 141.
Through such a configuration, one or more temporary power distribution devices 40 may communicate the existence of an emergency condition. Two or more connected temporary power distribution devices 40 may form a network of power distribution devices 140. When an emergency condition is determined by one of the temporary power distribution devices 40 in the network of power distribution devices 140, then the alert signal may be transmitted to other temporary power distribution devices 40 within the predetermined range and network of power distribution devices 140 and the audible alarm 120 and beacon light 122 may be activated. The a signal transmitting network device 128, a signal revieving network device 126, the audible alarm 120, and the beacon light 122 are preferably all powered by one or more of the group of: (1) the internal power reserve; and (2) power received from the external power supply. A power sensor 113 may be connected to the internal wiring 154 and configured to determine when to draw power from the internal power reserve 108 and which elements to allow to access the internal power reserve 108 or external power supply 102.
The emergency condition is meant to indicate when a danger for workers or nearby persons might exist. For example, power may be lost due to fire, earthquake, building or mine collapse, and the like. Alternatively, power may not be lost, but workers or persons near the temporary power distribution device 40 may be aware of some danger or emergency. Thus, an emergency condition may be triggered when at least one of the group of power supplied to the power input connection 100 via the external power supply 102 fails; the alert signal is received by the signal receiving network device 126 within a temporary power distribution device 128 from the wireless signal 141 emitted by the signal transmitting network device 128 of another temporary power distribution device 40; and the alarm activation button 123 disposed on the power station housing 42 is activated.
Referring to
It is preferred that at least some of the network of power distribution devices 140 be connected by retractable belts 132 connected to one of the temporary power distribution devices 40 and placed securely into the receptacle 134 of another temporary power distribution device 40. This configuration, as can be seen in
In some preferred embodiments, the device 40 may also include a video recorder 136 like a video camera. The video recorder 136 is meant to act in the manner of a flight data recorder in airplanes (sometimes known as a “black box”), recording images to determine the cause of an emergency condition or other emergency. The video recorder 136 may be positioned within the chamber 104 or maintenance cap 52 or may be positioned on the outside of the tower 44. The video recorder 136 may record video to its own internal hard drive or may transmit video wirelessly. In some preferred embodiments, the video recorder 136 may be connected to the signal transmitting network device 128 to better transmit video signal. The video recorder 136 is preferably connected to the internal power reserve 108 and external power supply 102 to ensure it does not lose power in an emergency. However, the video recorder 136 may contain its own power reserve or battery. Preferably, the video recorder 136, signal receiving network device 126, and signal transmitting network device 128 are connected to one the plurality of regulated electrical communication outlets 114 or a separate regulated electrical communication outlet positioned on the tower 44, to allow these components to be connected to a wireless communication device 116 via communication cord 118. Such a configuration may allow these components to be accessed, and their settings changed, via wireless communication device 116. In alternate preferred embodiments, these elements may be connected to the internet via wireless signal 141, allowing the settings of these elements to be changed via wireless communication devices 116 connected to the internet.
